A very shy guy went into a bar and saw a beautiful woman sitting at the bar.
After an hour of gathering up his courage he finally went over to her and asked, tentatively, "Um, would you mind if I chatted with you for a while?"
She responded by yelling, at the top of her lungs, "No I won't sleep with you tonight!"
Everyone in the bar was now staring at them.
Naturally, the guy was hopelessly and completely embarrassed and he slinked back to his table.
After a few minutes, the woman walked over to him and apologized. She smiled at him and said, "I'm sorry if I embarrassed you. You see, I'm a graduate student in psychology and I'm studying how people respond to embarrassing situations."
To which he replied, at the top of his lungs, "What do you mean $200?"
